Manual,  08/2006, A5E00105505-04 
3-91 
Technical data 
Lamp load  max. 50 W 
Wiring two outputs in parallel   
•  for redundant load control 
supported 
•  for performance increase 
not supported 
Control of a digital input  supported 
Switching frequency   
•  with resistive load 
max. 10 Hz 
•  with inductive load to IEC 947-5-1, AC 15 
max. 0.5 Hz 
•  with lamp load 
max. 1 Hz 
Short circuit-proof output  Yes, 3.15 A / 250 V fuse, fast-blow 
Wiring the actuators  with 20-pin front connector 
 
 
 
Note 
The outputs must be protected by a high-speed, fast-blow 3.15 A 250 VAC fuse. When 
installed in a hazardous area to National Electric Code, the area must be designated safe 
before you replace the fuse. Always use a suitable tool.
